The air bed further includes a surrounding band 300 provided on the sides of the novel cake-type air bed and between the top layer 100 and the bottom layer 200. The top layer 100, the bottom layer 200, and the surrounding band 300 enclose and form a cavity of the novel cake-type air bed. A distance between the top surface and the bottom surface of the novel cake-type air bed is a side width of the novel cake-type air bed, and the side width is greater than the width of the surrounding band 300. The top layer 100 and the bottom layer 200 extend to the sides of the novel cake-type air bed respectively, and are joined and bonded with the surrounding band 300.

Providing the surrounding band 300 enables the sides of the novel cake-type air bed to be flatter with more pleasing appearance. In addition, since the joining positions of the top layer 100 and the surrounding band 300 as well as the bottom layer 200 and the surrounding band 300 are both provided on the sides, the formed novel cake-type air bed is more attractive. Due to the fact that the joining positions are provided on the sides, the friction is reduced and a user cannot make contact with the seam line during sleep, which allows the user to sleep better and more comfortable and is more suitable for the demands of people.
